ROLL-TRAVERSE.

Application filed November 21, 1918.

To all whom it may concern.-

Be it known that I, JAMns A. KEs'rER, a citizen of the United States, residing at (iastonia, in the county of Gaston and State of North Carolina, have invented a new and useful Roll-Traverse, of which the following is a specification.

By way ofexplanation it may be stated that in a twister machine in a cotton mill, the material as it passes from the spools to the rollers not infrequently grooves the rollers because the material traverses the rollers in a fixed path, other disadvantages arising from the operation above alluded to.

In view of the foregoing, one object of the invention is to provide novel means for moving the material longitudinally of the rollers, as the material traverses the rollers.

The invention aims to provide novel means for operating the shift bars to cause the material to move longitudinally of the rollers, and to provide a simple structure which can be adapted readily to standard machines, without working expensive or appreciable changes in such machines.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

WVith the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings:

Figure'l shows in top plan, a device constructed in accordance with the invention; Fig. 2 is a section taken on the line 22 of Fig. 1; Fig. 3 is an elevation of the housing which contains certain working parts of the structure, the closure for the housing being removed; Fig. 1 is a section taken on the line l4 of Fig. 1; and Fig.v 5 a section taken on the line 55 of Fig. 4:.

In the drawings, the numeral 1 marks a part of the frame of a twister in a cotton mill, wherein the cotton, having been made into strands, is doubled and twisted. The spools are shown diagrammatically at 2, and the rolls are shown. diagrammatically Specification of Letters Patent.

at 3. The reciprocating shift bars appear at a, and carry guides 5 through which the material passes, between the spools 2 and the rolls 3. The shift bars 1% are provided with upstanding projections 7 receiving depending forks 8 on a cross piece ,9, supported at its ends on the shift bars, the cross piece 9 being connected at 10 at the diverging arms 11 of a pitman 12.

The pitman 12 passes into a slot 1 1 formed in a box-like housing 15, preferably of circular contour, the housing 15 being open at one side, to receive a removable closure 16 having projections 17 received in notches 18, screws 19 or the like being inserted into the housing 15, to hold the closure 16 in place, in combination with the projections 17 and the notches 18. The housing 15 is carried by a base 20 united by securing dcvice 21 with the frame 1.

That end of the pitman 12 which projects into the housing 15 through the slot 14, extends upwardly as shown at 22 and is mounted on a wrist pin 28 projecting from a gear wheel 24-located in the housing 15, a washer being interposed between the end 22 of the pitman and the gear wheel. The gear wheel 2% has ahub 25 journaled on a stub shaft 27 carried by the back wall of the housing 15.

The gear wheel 21 meshes into a pinion 28 secured to a shaft 29 journaled in the back wall of the housing 15 and disposed preferably at right angles to the pitman 12, as indicated in Fig. 1. The shaft 29 is received for rotation in a bearing 30 having an oil hole, the bearing being supplied with a depending fin 32 overlapping an upstanding flange 33 constituting a part of a support 3 1 including a base plate 35. There is an elongated. slot 36 in the fin 32 of the bearing 30, a clamp bolt 87 being adjustable in the slot, and being engaged with the flange 33 of the support 34. The base plate is provided with a slot 38 disposed at right angles to the slot 36 and receiving a clamp bolt 39 whereby the support 34 is secured to the frame 1. On the outer end of the shaft 29 there is fixed a worm wheel 40 having a hub 41 cooperating with one end of the bearing 80. Since the base plate 35 is supplied with the slot 38, the support 34: may be connected readily with the frame 1, depending upon the construction of the frame, and it is possible to adjust the bearing 30 longitudinally of the shaft 29, because the fin 32 has the slot 36. Consequently, the shaft 29 may be supported for rotation, but against longitudinal movement, the hub ll of the worm wheel 40 00- operating with one end of the bearing 30, and the pinion 28 cooperating with the back wall of the housing 15.

In practical operation, rotation is imparted to the shaft 29 by means of the worm wheel 40, the pinion 28 transmitting motion to the gear wheel 2%, the latter operat ing the pitman 12 through the instrumentality of the wrist pin The reciprocatory movement imparted to the pitman 12 is transmitted by the cross piece 9 and the forks 8 together with the projections 7 to the shift bars l, a longitudinal sliding move ment being imparted to the shift bars, and the guides 5 causing the material 6 to move longitudinally of the rolls 3 during the twisting operation. Since the material 6 is shifted longitudinally of the rolls 3, as above explained, the rolls will be kept clean and there will be no danger of grooving or injuring the rolls due to av repeated application of the material 6 to a single point on each roll.

It will be obvious that the closure 16 may be removed from the housing 15 at any time, thereby giving access to the gear wheel 24, the pinion 28 and to other parts of the structure which are located within the housing.

Having thus described the invention, what is claimed is 1. In a device of the class described,a pair of shift bars having projections; a cross piece having terminal forks receiving the projections; a pitman rigidly secured to the cross piece intermediate the ends of the ing the shaft.

2. In a device of the class described, a shift bar; a pitman; means for operatively connecting the pitman to the shift bar; a gear wheel whereunto the pitman is pivoted; a shaft; a pinion on the shaft and meshing into the gear wheel; a bearing receiving the shaft for rotation and including a depending fin provided with a extended longitudinally of the bearing; a support having an upstanding flange; and a. securing device located in the slot and cooperating with the flange.

3. In a device of the class described, a housing; a shaft journaled in the housing; a pinion on'the shaft and engaging the housing; a driving member on the shaft; a hearing on the shaft, between the driving member and the housing, the bearing cooperating with the driving member; a support; means for connecting the bearing with the support adjustably, to permit the bearing to cooperate with the driving member; a gear wheel journaled in the housing and meshing into the pinion; a shift bar; and means for operatively connecting the shift bar with the gear wheel.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in'the presence of two witnesses.
